public class AgentXFrequencyModel
extends OpponentModel

Class for building an opponent model in discrete space. Contains value- and issue-processors to deal with opponent bids. Adapted by Mark Hendrikx to be compatible with the BOA framework.

public AgentXFrequencyModel()

Method Detail

init

public void init(NegotiationSession negotiationSession,
                 java.util.HashMap<java.lang.String,java.lang.Double> parameters)
          throws java.lang.Exception

Creates an opponent model for the given utility space

Overrides:

init in class OpponentModel

Parameters:

u - The utility space

Throws:

java.lang.Exception

getValueProcessor

public negotiator.boaframework.opponentmodel.agentx.DiscreteValueProcessor getValueProcessor(IssueDiscrete i)

Returns a DiscreteValueProcessor, allowing the use of several methods

Parameters:

i - The issue for which a ValueProcessor is needed

Returns:

a DiscreteValueProcessor for the issue

getIssueProcessor

public negotiator.boaframework.opponentmodel.agentx.DiscreteIssueProcessor getIssueProcessor()

Gives the discreteIssueProcessor for this opponent model

Returns:

The discreteIssueProcessor

updateModel

public void updateModel(Bid b,
                        double time)

Processes a bid, possibly changing value ranks for the internal opponent model. Currently, values on which more bids are made are ranked higher.

Specified by:

updateModel in class OpponentModel

Parameters:

b - The bid done by the opponent

time - Time at which the bid was done

getEvaluationOfValue

public double getEvaluationOfValue(int issueIndex,
                                   ValueDiscrete valueOfIssue)

Gives the normalized value rank of some value within a certain Issue

Parameters:

issueIndex - The index of the issue. Same index as in the ArrayList provided by utilitySpace.getDomain().getIssues()

valueOfIssue - The value from that issue for which the normalized rank is required

Returns:

The normalized valueRank for the value of the issue given

getBidEvaluation

public double getBidEvaluation(Bid bid)

Calculates the utility to our opponent of the bid received as a parameter using the current knowledge given by our opponent model

Overrides:

getBidEvaluation in class OpponentModel

Parameters:

bid -

Returns:

utility value for our opponent

getWeight

public double getWeight(Issue issue)

Description copied from class: OpponentModel

Returns the weight of a particular issue in the domain.

Overrides:

getWeight in class OpponentModel

Parameters:

issue - from which the weight should be returned

Returns:

the weight of the issue.

getOpponentUtilitySpace

public UtilitySpace getOpponentUtilitySpace()

Overrides:

getOpponentUtilitySpace in class OpponentModel

Returns:

utilityspace created by using the opponent model adapter.

getName

public java.lang.String getName()

Overrides:

getName in class OpponentModel

Returns:

name of the opponent model.
